ANNUNCIATOR AND FIRE TELEGRAPH.

' SEBCIPICATION forming part of Letters Patent No. 317,569, dated May 12,1885.

Application filed July 23, 1883. (X0 model.)

To ctZZ whom it may concern:

Be it known that 1, CHARLES K. PEVEY, of the city and county of Worcester, in the Commonwealth of Massachusetts, have invented a new and useful Improvement in Electric-Annnnciator Alarms; and I do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawing, which forms a part of this specification.

The object of my invention is to provide better and more desirable means whereby guests in hotels and boarding-houses can be aroused from sleep in case they wish to be, called at certain hours for departure, and in case of fire, and by which the person in charge at the office can give the alarm to one room or to all of the rooms in the house simultaneously without running from room to room, and can also be made to answer the purpose of a call-bell from the sleeping-room to the office.

My invention consists of the arrangement of an alarm bell and double or single acting swing-switch or a press-button switch in one or more sleeping-rooms, connected by means of electric main battery and circuit-wires with a switch, and also with the annunciators now in use in the oftlce or other room, so that when the switch in the sleeping-room is closed on the bell andthe switch in the office,being open, is moved to close the circuit it will set the bell ringing continuously in the sleeping-room until the person is aroused sufliciently to get up and switch it off, in doing which with the doubleacting switch it will announce the fact of his being up at the oflice through the annunciator without the use of the push-button switch, so that the push-button may or may not be used for this purpose, and can be used at any time from the room to the ofiice, if desirable.

By this device the customary unpleasant way of rousing sleepers by rapping and calling at the door vocally, so annoying to the adjoining occupants, is avoided, besides it is often the case that a person when called in that manner will,half asleep and half awake, answer the call and. drop immediately asleep again, and he is left to sleep it out, andfindhe haslosthis train or failed to meet some important engagement; but with my device the bell is kept ringing by the electric connections until the person gets up and switches it off in his room, and he will not be likely to turn into bed again.

To enable others skilled in the art to put up and practice my invention, I will proceed to describe its construction and operation.

Referring to the accompanying drawing, A denotes the office-room, and A the sleepingroom.

13 denotes the electric batteries,which may be located in any convenient place.

E denotes a swing-switch in the office, and

E a double-acting swing-switch in the sleep ing-room A, with bell E and a push-button switch, G.

Electric main battery-wireD extends through all the rooms to complete a circuit. Wire Ois a circuit-wire extending from the battery to screw P under the lower end of swing-switch E to the right,and circuit-wire Cconnects to the pivot-screw P of switch E,and extends to screw 0 under the lower end of switch E to the right circuitwire K, is fastened to pivot screw 0 of switch E, and extends to bell F. Circuitwire J extends from bell F to battery-wire D, which completes this circuit with bell F and the batteries. Circuit-wire C is attached one end to battery-wire G and the other end to screw 0 in switch E. Circuit-wire J is attached one end to said screw 0 and the other end to the same screw that circuit-wire J is attached to under the push-button switch G, and thence to bell H, which has connection with the drop-tag magnet H by means of circuitwire J, thence to the main battery-wire D by means of circuit-wire J which completes this branch of the circuit. The push-button switch G is operated by through bell H and the drop-tag A to battery-wire D by wires J and J which completes this branch of the circuit. I

The arrows indicate the direction of the electric current, and a a the stop-pins of the switches, and the dotted lines the movement of the switches.

This device can in like manner be extended to any number of rooms.

To operate this invention switch E in the sleeping-room should be set to the right, which closes the circuit on bell E at this point, as shown, left, as shown, so that when moved to the right the circuit-wires G and J and switch E in the office set to the it will close the circuit at this point through to bell F and set it ringing continuously until the sleeperis aroused sufficiently to get up and move switch E to the left onto pin 0,which shifts the, circuit onto wires (3 and J, and wire Junder the push-button G,whieh extends to the bell H,and thence by wire J to the drop tag A ofthe an nunciator-magnet H, and thence by wire J, which completes this branch of the circuit with the main battery-wire D, and the batteries, thus announcing the fact that the person is up.

Switch E should be left midway, as shown by the dotted lines, when not in use.

The push-button switch can be used for a call or notice from the room to the office at any time, if desired, without interfering with my device.

CHARLES K. PEVEY.
